SILOXA container-based gas supply system for biogas with gas drying
module, gas compression module and controller, GCKV model
Gas cooler
– Tube bundle heat exchanger
– Max. permissible operating pressure: tube side approx.
0.5 bar, shell side approx. 6 bar, pressure loss on gas
side approx. 15 mbar
Water cooler
– Air-cooled condensers for outdoor installation
and all-year operation
– Compact, commercially produced standard unit
Liquid coolant circuit
Attributes
– Compact design, modular structure
– High availability, operational reliability, low maintenance
– Possibility of upgrading with further modules/options
– Dened interfaces to fermenters, gas utilisation system and the customer's process control system
Container
– External dimensions: L x W x H
approx. 3,050 x 2,500 x 2,600 mm
or approx. 6,100 x 2,500 x 2,600 mm
(depending on the ow rate)
– Aluminium tread plate oor
– Double door, external hinges, all-round rubber seal,
door opening 2,310 x 2,280 mm
– Primed inside and outside, exterior painted in RAL
6005, custom colour possible if desired subject to
a surcharge
– Electrical installation: 1 light switch, 2 sockets:
230 V16 A, 2 strip lights, 1 thermostat-controlled
ventilator with axial ow fan
– Side entrance door
Ambient air monitoring
– Sensor for ATEX Zone II 2G (Ex Zone 1 and 2),
measuring principle: evolution of heat,
measuring range: CH40…100 %LEL
– Evaluation unit in control cabinet on the container
which triggers an alarm and switches off the power
supply to the assemblies in the container if the limit
value is exceeded; power supply provided
by customer

– Pipework material:steel incl. ange,
screws and gaskets
– Required manual and safety valves
and local-readout thermometer and manometer
Condensate trap
– Moulded piece, material No. 1.4571,
for ange-mounting on gas cooler DN 150-400
– Demister, material No. 1.4571
– Condensate outlet via liquid shut-off valve
– Monitoring of liquid shut-off valve via rod probe
with 2 switching contacts
Cold insulation
– Vapour-diffusion-proof insulation for gas drying
system, condensate trap, condensate outlet and
liquid coolant circuit
Compressor
– 1 centrifugal fan (multistage)
– Pressure increase 160 mbar
– V-belt drive with aluminium drive guard
– Permanently technically leakproof,
ATEX approved for Zone 2
– 1 pressure monitor on the suction side
of the compressor and 1 on the pressure side
– 1 temperature monitor
– To limit the discharge pressure and ensure
a minimum ow rate (surge limit):
• Pressure regulator including bypass up to 600 Nm3/h
• Frequency converter from 750 Nm3/h
